AI Article Synopsis

  • The study investigates the link between perinatal sentinel events (PSE) and MRI/neurodevelopmental outcomes in newborns with hypoxic-ischemic encephalopathy (HIE) receiving therapeutic hypothermia (TH).
  • Out of 182 neonates analyzed, those with PSE showed a higher percentage of normal MRIs and better motor and language outcomes compared to those without PSE.
  • The findings indicate that neonates with PSE experienced less severe brain injury and improved developmental outcomes at 18-36 months after TH treatment.

Article Abstract

Objective: To study the association between perinatal sentinel events (PSE) and brain MRI/neurodevelopmental outcomes in neonates with hypoxic-ischemic encephalopathy (HIE) receiving therapeutic hypothermia (TH).

Design: This is a retrospective single-center study. Data collection included perinatal history, brain MRI, and neurodevelopmental outcome.

Results: Out of the 182 neonates, 53 (29%) neonates had PSE and 129 (71%) neonates did not have PSE. Neonates with PSE had more normal MRIs (76%) compared with neonates without PSE (55%), p = 0.01. PSE was associated with favorable motor (p = 0.02), language outcome (p = 0.03), and trend to better cognitive scores (p = 0.13). In PSE, favorable motor outcome persisted (OR for impairment 0.15 (0.003-0.84), p = 0.03) after adjusting for the degree of encephalopathy and brain MRI injury. Injury on brain MRI despite TH after PSE was associated with unfavorable neurodevelopmental outcome (p < 0.001).

Conclusion: Neonates with HIE receiving TH after PSE had less severe injury on brain MRI after rewarming, and improved motor and language outcomes at 18-36 months.

Unlabelled: Premature children with bronchopulmonary dysplasia (BPD) encounter several health issues potentially affecting their health-related quality of life (HRQL). We aimed to determine agreement between children with BPD and their parent's HRQL assessments. Using Patient-Reported Outcomes Measurement Information System (PROMIS) assessment tools, we evaluated agreement and potential bias between parent proxy and child self-reports of the PROMIS-Scale-Global Health-7, the Psychological Stress Experiences Short Form (PSE), and the PROMIS-Profile-25.

Anomalies of the fourth branchial cleft are exceedingly uncommon, presenting with a diverse array of clinical manifestations. The majority of branchial cleft anomalies, approximately 95%, are of the second type, with a mere 2% attributed to the fourth type. The latter is notably more prevalent on the left side, with reports indicating an 85% incidence.

Article Synopsis
  • * The research used data from 2012 to 2019, analyzing records of neonates diagnosed with PSE/NAS and instances of community violence to identify geographic and temporal patterns.
  • * Results indicated significant clustering of PSE/NAS with community violence and gun violence, suggesting that targeted resource allocation to high-risk areas could enhance health outcomes in vulnerable populations.

Article Synopsis
  • Waardenburg syndrome (WS) is a genetic disorder that leads to pigment abnormalities and hearing loss, and this case report discusses a rare instance in a preterm infant who had multiple congenital anomalies.
  • The baby, born at 35 weeks, showed classic WS features like a white forelock and required intensive care for respiratory and feeding issues, along with further complications involving his heart and kidneys.
  • The report emphasizes the need for multidisciplinary care and early intervention to improve outcomes for infants with WS, especially highlighting the unexpected presence of cardiac and renal anomalies in this case.
